[0002] In the field of manufacturing electrical switching devices such as relays and contactors, the dynamic spring group, as a key functional component, directly affects the performance and production efficiency of the entire electrical product. A current dynamic spring group is composed of a base plate, a movable contact, and a V-shaped spring sheet with specific mechanical properties. The base plate, as a load-bearing and positioning base component, is located on the inner side of the V-shaped spring sheet. The two are tightly fixed together by riveting process through the movable contact, forming a combined structure with stable electrical connection and mechanical action function.

The dynamic spring group needs to be precisely transported to the assembly station one by one to realize accurate docking and assembly with other workpieces prepared in advance on the station. Any slight deviation may affect the performance of the entire electrical switching device. However, the current industry widely adopts manual feeding method, which is not only time-consuming and labor-intensive, but also difficult to ensure the assembly precision and quality of the dynamic spring group due to the randomness and uncertainty of manual operation.

[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0044] The present application provides a novel feeding mechanism for movable spring groups, which is used to solve the problem of how to automatically feed and assemble movable spring groups 7.

[0045] Referring to Figure 1 as shown, Figure 1 The novel feeding mechanism for movable spring groups in the example includes a frame 1, a feeding mechanism 2, a material distributing mechanism 3, and a transfer mechanism 4.

[0046] The feeding mechanism 2 is installed on the frame 1 and is used to continuously feed movable spring groups 7 one by one.

[0047] The distributing mechanism 3 is installed at the discharging end of the feeding mechanism 2, and is used to receive the dynamic spring group 7 output by the feeding mechanism 2 and transfer the dynamic spring group 7 to the feeding station one by one.

[0048] The transferring mechanism 4 is installed on the frame 1, and is used to transfer the dynamic spring group 7 on the feeding station to the assembling station for assembling.

[0049] When the dynamic spring group novel feeding mechanism is used, first, the feeding mechanism 2 outputs the dynamic spring group 7 one by one; then, the distributing mechanism 3 receives one dynamic spring group 7 output by the feeding mechanism 2 each time and transfers the dynamic spring group 7 to the feeding station; finally, the transferring mechanism 4 transfers the dynamic spring group 7 on the feeding station to the assembling station for assembling. It can be seen that the dynamic spring group novel feeding mechanism can realize automatic feeding of the dynamic spring group 7 to the assembling station one by one through the cooperation of the feeding mechanism 2, the distributing mechanism 3 and the transferring mechanism 4, and replaces manual feeding and assembling, thereby greatly improving the assembling efficiency and quality stability, solving the efficiency and quality problems caused by manual feeding and assembling, and reducing the labor intensity.

[0050] The feeding mechanism 2 can be formed by combining the existing vibration disc 21 and the straight vibrator 22, or can be formed by combining a flexible vibration disc and a mechanical hand, etc. In the embodiment, the feeding mechanism 2 uses the first embodiment.

[0051] Referring to FIGS. 1, 2 and 3, Figure 1 , Figure 2 and Figure 3 , Figure 2 FIG. 4 is a structure schematic view of the movable block in the first position and the feeding track and the movable block driving assembly in the embodiment, Figure 3As shown in the structural schematic view of the movable block in the second position and the feeding track and the movable block driving assembly in the embodiment, on the basis of the above embodiment, the feeding mechanism 2 comprises a feeding track 221 for feeding the dynamic spring group 7 one by one. The distributing mechanism 3 comprises a movable block 31 and a movable block driving assembly 32. The movable block 31 is rotatably installed at the discharging end of the feeding mechanism 2. The movable block 31 has a loading part 311 for carrying a single workpiece. The loading part 311 and the feeding track 221 are both V-shaped and similar to the shape of the dynamic spring group 7. The plane where the rotation track of the movable block 31 is located is arranged perpendicularly to the feeding track 221. The movable block driving assembly 32 is installed on the rack 1 and is in transmission connection with the movable block 31. The movable block driving assembly 32 is used to drive the movable block 31 to rotate reciprocally between the first position and the second position. When the movable block 31 is in the first position, the loading part 311 is aligned with the feeding track 221 to receive the workpiece on the feeding mechanism 2. When the movable block 31 is in the second position, the loading part 311 is located in the loading station. In this way, when loading, the initial position of the movable block 31 is the first position. First, the feeding mechanism 2 outputs a single dynamic spring group 7 to the loading part 311 aligned with the feeding track 221 through the feeding track 221. Then, the movable block driving assembly 32 drives the movable block 31 to rotate to the second position, so as to transfer the loading part 311 and the dynamic spring group 7 thereon to the loading station for the transferring mechanism 4 to transfer and assemble. Finally, the movable block driving assembly 32 drives the movable block 31 to return to the first position, so that the feeding mechanism 2 outputs the next dynamic spring group 7 to the loading part 311. As can be seen, the distributing mechanism 3 drives the movable block 31 to flip through the movable block driving assembly 32. Not only can the dynamic spring group 7 output by the feeding mechanism 2 be separated and moved out one by one, but also the flipping of the dynamic spring group 7 can be realized to stand up the base plate 71 of the dynamic spring group 7, so as to facilitate the subsequent transferring mechanism 4 to grasp the base plate 71 to assemble the dynamic spring group 7. The transferring mechanism 4 grasps the base plate 71 instead of other parts, which can protect the dynamic spring group 7 from being damaged or deformed in the process of grasping and assembling.

[0052] Referring to Figure 1 , Figure 2 and Figure 3As shown in the first embodiment of the movable block driving assembly 32, the movable block driving assembly 32 comprises a telescopic driving member 321 and an elastic member 322. Two ends of the elastic member 322 are connected with the rack 1 and the movable block 31 respectively. The telescopic driving member 321 is arranged on the rack 1 by screwing or welding. The movable block 31 is in abutment with the output end of the telescopic driving member 321 under the elastic force of the elastic member 322. The telescopic driving member 321 and the elastic member 322 are combined to drive the movable block 31 to reciprocate between the first position and the second position. As can be seen, the telescopic movement of the telescopic driving member 321 can push the movable block 31 to reciprocate and switch between the first position and the second position flexibly, because the movable block 31 is always in abutment with the output end of the telescopic driving member 321 under the elastic force of the elastic member 322.

[0053] The elastic member 322 can be a spring belt, a tension spring or a compression spring, etc.

[0054] On the basis of the above embodiments, a stop block (not shown in the figure) can be arranged at the first position and the second position respectively to accurately control the rotation of the movable block 31 to the first position or the second position.

[0055] In the second embodiment of the movable block driving assembly 32, the movable block driving assembly 32 comprises a turnover driving member (not shown in the figure). The turnover driving member is arranged on the rack 1 by screwing or welding and is in transmission connection with the movable block 31. The turnover driving member is used to drive the movable block 31 to reciprocate between the first position and the second position. As can be seen, the turnover driving member can directly drive the movable block 31 to reciprocate, and the driving structure is simple and direct.

[0056] The turnover driving member can be a rotary air cylinder or a stepping motor.

[0057] Referring to Figure 1 , Figure 2 and Figure 3 As shown in any of the above embodiments, the rack 1 comprises a limiting block 11 located at the feeding station. When the movable block 31 is at the second position, a limiting groove 5 is formed between the limiting block 11 and the load carrying part 311, and the limiting groove 5 is used to accommodate and limit part of the dynamic spring set 7. In this way, the turnover of the dynamic spring set 7 by the distributing mechanism 3 causes the substrate 71 of the dynamic spring set 7 to stand up, and at the same time, the limiting groove 5 limits the turned-over dynamic spring set 7, so that the substrate 71 of the dynamic spring set 7 remains in the standing-up state to be grabbed by the subsequent transfer mechanism 4, and effectively avoids the turned-over dynamic spring set 7 from falling off the load carrying part 311.

[0058] Referring to Figure 1 and Figure 4As shown, Figure 4 The left view of the transfer mechanism in the embodiment shows that, in one implementation of the transfer mechanism 4, the transfer mechanism 4 includes a two-axis drive assembly 41, a deflection drive member 42, and a clamp 43. The two-axis drive assembly 41 is mounted on the frame 1, and its output end is connected to the deflection drive member 42. The output end of the deflection drive member 42 is connected to the clamp 43. The two-axis drive assembly 41 drives the deflection drive member 42 and the clamp 43 to move along the discharge direction of the feeding mechanism 2 and / or the depth direction of the limiting groove 5; the deflection drive member 42 drives the clamp 43 to tilt or flip, and the plane of the tilting or flipping trajectory of the clamp 43 is perpendicular to the feeding track 221; the clamp 43 is used to clamp or release the moving spring assembly 7. Thus, after the material distribution mechanism 3 flips the movable spring assembly 7 to the loading station, the two-axis drive assembly 41 drives the clamp 43 to move above the limiting groove 5, and the clamp 43 clamps the upper end of the base plate 71 of the movable spring assembly 7; then, the two-axis drive assembly 41 drives the clamp 43 to move upward along the depth direction of the limiting groove 5 to pull the movable spring assembly 7 out of the limiting groove 5; finally, the two-axis drive assembly 41 drives the clamp 43 and the movable spring assembly 7 to the assembly station for assembly. During the assembly process, the clamp 43 is tilted or flipped by the deflection drive 42, which can cause the movable spring assembly 7 to tilt or flip accordingly, so that the movable spring assembly 7 can be smoothly assembled onto the workpiece.

[0059] The aforementioned two-axis drive assembly 41 can be formed by combining two linear drive mechanisms such as telescopic cylinders or telescopic rods. The two linear drive mechanisms are respectively used to drive the clamp 43 to move along the discharge direction of the feeding mechanism 2 and the depth direction of the limiting groove 5. The aforementioned deflection drive 42 can be a rotary drive mechanism such as a rotary cylinder or a stepper motor, with its output end fixedly connected to the clamp 43. In this way, the rotary drive mechanism can directly drive the clamp 43 to tilt or flip. Alternatively, the aforementioned deflection drive 42 can be a telescopic drive mechanism such as a telescopic cylinder or telescopic rod. Both the telescopic drive mechanism and the clamp 43 are rotatably connected to the output end of the two-axis drive assembly 41. The output end of the telescopic drive mechanism is rotatably connected to the clamp 43. In this way, the telescopic drive mechanism can also drive the clamp 43 to tilt or flip when it extends or retracts. In this embodiment, the deflection drive 42 uses the latter implementation.

[0060] See Figure 1 and Figure 5 As shown, Figure 5For the perspective view of the material blocking mechanism and the feeding track in the embodiment, on the basis of any of the above embodiments, the new spring set feeding mechanism further comprises a material blocking mechanism 6 installed upstream of the material distributing mechanism 3. The material blocking mechanism 6 comprises a first blocking block 61 and a first blocking block driving member 62. The first blocking block driving member 62 is installed at the discharging end of the feeding track 221 and is in driving connection with the first blocking block 61. The first blocking block driving member 62 is used to drive the first blocking block 61 to move towards or away from the feeding track 221, so as to press or release the next spring set 7 at the discharging end of the feeding track 221. In this way, after the feeding mechanism 2 outputs the single spring set 7 to the material loading part 311 aligned with the feeding track 221 through the feeding track 221, the first blocking block driving member 62 drives the first blocking block 61 to move towards the feeding track 221, so as to press the next spring set 7 at the discharging end of the feeding track 221, so that the feeding mechanism 2 does not continue to output the spring set 7 when the movable block driving assembly 32 drives the movable block 31 to move away from the first position. Until the movable block 31 returns to the first position, the first blocking block driving member 62 drives the first blocking block 61 to move away from the feeding track 221, so as to release the next spring set 7 at the discharging end of the feeding track 221, so that the feeding mechanism 2 can output the next spring set 7 to the material loading part 311 again.

[0061] The above-mentioned first blocking block driving member 62 can use a linear driving mechanism such as a telescopic air cylinder or a telescopic electric rod.

[0062] Referring to FIGS. 1, 2 and 3, Figure 1 and Figure 5 on the basis of the above-mentioned embodiment of the material blocking mechanism 6, the material blocking mechanism 6 further comprises a second blocking block 63 and a second blocking block 63 driving member. The second blocking block 63 driving member (not shown in the figure) is installed at the discharging end of the feeding track 221 and is in driving connection with the second blocking block 63. The second blocking block 63 driving member is used to drive the second blocking block 63 to move towards or away from the feeding track 221, so as to block or open the discharging end of the feeding track 221. In this way, the first blocking block 61, the first blocking block driving member 62, the second blocking block 63 and the second blocking block 63 driving member cooperate to effectively control whether the feeding mechanism 2 outputs the spring set 7, and further effectively avoid the spring set 7 from being inadvertently leaked out of the feeding mechanism 2 and the material distributing mechanism 3.

[0063] The above-mentioned second blocking block 63 driving member can use a linear driving mechanism such as a telescopic air cylinder or a telescopic electric rod.

[0064] In addition to the above-mentioned material blocking mechanism 6 further comprising a second blocking block 63 and a second blocking block 63 driving member, the material blocking mechanism 6 can further comprise the second blocking block 63 but not the second blocking block 63 driving member. The second blocking block 63 is arranged on the movable block 31 by screwing or integral connection or the like. When the movable block 31 is in the second position, the second blocking block 63 blocks the discharge end of the feeding track 221. In this way, the present embodiment drives the movable block 31 to rotate to the second position by the movable block driving assembly 32, so as to drive the second blocking block 63 to rotate to the discharge end of the feeding track 221, thereby blocking the discharge end of the feeding track 221. In cooperation with the first blocking block 61 and the first blocking block driving member 62, the material blocking mechanism 6 can further effectively prevent the moving spring group 7 from inadvertently leaking out of the feeding mechanism 2 and the material distributing mechanism 3, and can also save the driving cost.

[0065] Referring to FIGS. 1-3, Figure 1 and Figure 5 As shown in the above-mentioned material blocking mechanism 6, the material blocking mechanism 6 further comprises an adjusting driving member 64. The adjusting driving member 64 is installed on the rack 1, and the output end of the adjusting driving member 64 is connected with the first blocking block driving member 62. The adjusting driving member 64 is used to drive the first blocking block driving member 62 and the first blocking block 61 to displace along the extension direction of the feeding track 221. It can be seen that the material blocking mechanism 6 can adjust the material pressing position of the first blocking block 61 by the adjusting driving member 64, thereby improving the material blocking precision and flexibility.

[0066] The above-mentioned adjusting driving member 64 can use a telescopic air cylinder, a telescopic electric rod or the like linear driving mechanism.

[0067] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
